19.1. Alternate Network Configurations Overview

In the alternate network
configurations, the Sun Ray server is also used as a DHCP
server. Using a shared network configuration with external DHCP
services is the recommended way to set up a Sun Ray environment,
which is described in
Chapter 2, Planning a Sun Ray Network Environment.

The utadm command is used to manage the Sun
Ray network interfaces. Note the following information:

If the IP addresses and DHCP configuration data are not set
up properly when the interfaces are configured, then the
failover feature will not work as expected. In particular,
configuring the Sun Ray server's interconnect IP address as
a duplicate of any other server's interconnect IP address
may cause the Sun Ray Authentication Manager to generate
"Out of Memory" errors.

If you make manual changes to your DHCP configuration, you
will have to make them again whenever you run
utadm or utfwadm.

(Oracle Solaris only) If you press CTRL-C while performing
utadm configuration, utadm might not function
correctly the next time it is invoked. To correct this condition, type dhtadm
-R.
